SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

STM32F4 DMA Interrupt big latency :(


Hi Aditya,

What kind of slowdown do you notice? Of course unoptimized code runs slower than optimized one, but, except if you are very close to the maximum MCU load, it should not be noticeable (except, of course, if you measure it in your code)...

As for the other IDEs, I can’t say but they may not optimize like GCC. Of course it is possible you ran in a GCC bug, but that is very improbable; I would rather bet that some code is not clean enough (either ST’s or your’s) and fools the optimizer...
